LIFTING DEVICE.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application filed April 5, 1919. Serial No. 287,725.

To all whom it may concern:

Be it known that I, WILLIAM P. Tom), a citizen of the United States residing at Princess Anne, in the county. of Somerset for use in connection with vehicle bodies,-

and it is an object of the invention to provide a novel and improved device of this character which may be employed with convenience and facility by a single person for loading or unloading a vehicle.

It is also an object of the invention to provide a novel and improved device of this general character including a jib sup-ported for rotary movement and which is also capable of swinging movement into and out of operative position and wherein a block and tackle or the like is supported by the jib.

Another object of the invention is to provide a device of this general character having novel and improved means whereby the same may be effectively secured to a vehicle body or the like.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved lifting device whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a fragmentary view in elevation illustrating a lifting device constructed in accordance with an embodiment of my invention, and

Fig. 2 is a fragmentary view partly in end elevation and partly in section of the structure as illustrated in Fig. 1.

In practice, my improved lifting device is particularly adapted for use in connection with the rear of a vehicle body, and, as dis closed in the accompanying drawings, A denotes a rear axle having arranged thereabove a, bolster B and which bolster is providlecg adjacent an end thereof with a standarc My improved lifting device comprises a table 1 carried by the upper end portions of the spaced straps 2 and which straps are adapted to be arranged at opposite sides of a standard S and secured thereto through the medium of the bolts 3 or the like. The opposite or lower end portions of the straps 2 are provided with the inwardly facing jaws t which are adapted to snugly clamp the axle A through the medium of the setscrews 5 or the like.

In swivel connection with the table 1 and having rotary movement in a horizontal plane is a plate 6 provided with the upstanding ears or lu 's 7. Extending between the ears or lugs 7 and pivotally engaged therewith for swinging movement in a vertical plane is the jib 8.

When the jib is not in use, the same may be readily swung to lie in close proximity to the wagon body or box, but when it is desired to employ my device, the jib is swung upwardly and which movement is limited by the contact of the pivoted end of said jib with the plate 6.

The upper or free extremity of the jib 8 is provided with an eye 9 or the like to afford means whereby the upper pulley of a block and tackle or other hoisting means may be engaged therewith and it is preferred that the upper pulley P be of a differential type, although I do not wish to be understood as limiting myself in this respect. Coacting with the block and tackle is a grapple G or other engaging means so that my improved lifting device may be conveniently employed in loading or unloading the vehicle to which it is applied.

From the foregoing description, it is thought to be obvious that a lifting device constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

It is to be understood that my improved descri tion and illustration thereof be given.-

1. A lifting device of the class described comprising, in combination with an axle and a c'oacting bolster of -a"ve'hicle,' a table,

straps depending from said table and extending across opposite sides of the bolster "and axle, means for securin the straps to the bolster and axle, ajibsupported by the across "opposite sides of the bolster and axle,

means for securing the straps to the bolster and axle, a plate rotatably support-ed by the table, a jib pivotall'y engaged with the plate for swinging movement in a direction a'ngular to'tlie axis er rotation of the plate, and

hoisti-i'ig 'means c'oacting with the jib.

In testimonywhereof I hereunto aflix my signature in't'he presence of two witnesses.
